Use for novels and stories dealing with the detection and solution of crime. Where possible assign additional topical headings, e.g. a class-of-persons heading for the investigator, or a heading for the name of the investigator, and headings for the setting and for the crime involved.
Taken from the French word meaning "darkness" or "of the night," noir is a category of modern crime fiction. Use this term for fiction of crime and detection, often in a grim urban setting, featuring petty, amoral criminals and other down-and-out characters, and permeated by a feeling of disillusionment, pessimism and despair. Examples include Jim Thompson's Hardcore and James M. Cain's The postman always rings twice.
Use for works dealing with witchcraft, spiritualism, psychic phenomena, voodooism, etc., and for works dealing with the mysterious or secret knowledge and power supposedly attainable only through these and other magical or supernatural means.
